Tons of changes, some big some small, and IAS is verified to be a 50% nerf. Most interesting to me is the major drop in crafting costs for items lvl 59 and down, however the gem crafting changes won't make much of a difference to folks in the end game as it only applies to gems which naturally drop anywise. Higher end gems are still stupid expensive to make, and thus quite prohibitive.

Edit: and yeah, I only had one IAS item (gloves) which now reports 7% vice 15% and I dropped down to 7.8K DPS from around 8.8K DPS.
